Review of Cognitive and Adolescent Development

Criticisms of Piaget's Theory of Cognitive Development

  • Discontinuous vs. Continuous Development: One of the biggest criticisms of Piaget's theory, which posits development occurs in distinct stages, is that it suggests a discontinuous process. Critics argue that development is inherently continuous, not discontinuous. For example, it's not accurate to claim a 9-year-old can never think like a 14-year-old.
  • Environmental Influence: The theory overlooks the crucial role of the environment. Children with parents who encourage learning and provide better resources may develop cognitive skills at different rates than those whose parents do not prioritize learning. Therefore, development cannot be rigidly confined to stages without considering environmental factors.
  • Gradual Shifting and Concurrent Stages: Modern interpretations and criticisms emphasize that children shift gradually in their thinking over a wider range of ages than Piaget suggested. They can also demonstrate thinking skills associated with more than one stage simultaneously, challenging the idea of distinct, linear progression through stages.
  • Western-Centric Bias: Piaget's theories have been criticized for being Western-centric. He did not adequately account for how different cultures might influence the learning of various skills or how cultural contexts could lead to different developmental paces and ages for progressing through these proposed stages. This indicates a limitation in the theory's universality.

Language Development

Language development is a crucial aspect of cognitive development and typically unfolds in five stages.

  • Innate Readiness: Infants are born ready to learn language and show a preference for the language spoken by their parents, not only from birth but also prenatally.

5 Stages of Language Development:

  1. First Verbal Cues: This initial stage involves basic verbal sounds such as gurgling, crying, and grunts. These are the earliest forms of verbal communication.
  2. Babbling: In the second stage, infants begin to babble. This stage demonstrates clear intent, though there is no specific meaning yet. It starts with single consonants and progresses to syllables (e.g., "ba ba ba ba"). Unlike the random noises of the first stage, babbling indicates an intention in the sounds being made.
  3. One-Word Stage: Occurring around the end of the first year, children enter the one-word stage. They learn to combine two single words to communicate their needs. Examples include "go park," "go potty," or "kitty milk," where essential words are put together to express a desire.
  4. Telegraphic Speech: In this fourth stage, vocabulary rapidly expands, and children begin to form mini-sentences. This is known as telegraphic speech. These sentences often lack many words, especially grammatical markings, but still convey clear meaning and follow a logical syntax (e.g., "throw ball all gone" when a toddler throws a ball). Psychologist Roger Brown coined this term, highlighting how these concise sentences, despite missing words, communicate a wealth of meaning.
  5. Overregularization: The final stage is characterized by more complex language, but children tend to overapply grammatical rules. For instance, they learn that adding "-ed" makes a verb past tense and might incorrectly say "ranned" or "holded" instead of "ran" or "held." This phenomenon, called overregularization, is significant because it demonstrates that children understand patterns in language development and are not merely imitating sounds. It shows active cognitive function in recognizing and applying linguistic rules, even if incorrectly at first. From this point, their vocabulary continues to grow throughout their lives.

Adolescent Development

Adolescence involves significant physical, social-emotional, and cognitive development.

Physical Development: Puberty

  • Primary Marker: Puberty is the most significant physical marker of adolescence. It involves physical changes in the body related to sexual development.
  • Growth Spurt: Adolescents experience a rapid growth spurt, a rate of growth only paralleled during infancy (from 0 to 2 years of age).
  • Secondary Sex Characteristics: These are physical changes during puberty not directly related to reproduction. Examples include the growth of body hair, breast development in girls, voice deepening and jaw angularity in boys, and girls gaining fat around the hips.
  • Primary Sex Characteristics: These are physical changes during puberty that directly result in sexually mature reproductive organs and genitals. Examples include the production of eggs and sperm, which are essential for reproduction.

Brain Structure Changes in Adolescence

  • Neural Refinement: The brain undergoes significant changes, including the refinement of synaptic (neural) connections, and an increase in gray matter.
  • Frontal Cortex Development: The frontal cortex, responsible for executive functions like planning and decision-making, is not fully developed until the early twenties.
  • Limbic System Activity: The limbic system, the brain's motivational and emotional center, is highly active during adolescence—even more so than the developing frontal cortex. This explains why adolescents tend to be more emotional and make decisions based on feelings rather than logic.

Quest for Identity

Adolescence is a period of intense identity exploration, where individuals seek to understand who they are, what they like, and their preferences, developing a sense of self and independent thought.

  • Influencing Factors: The development of self-identity is influenced by various factors:
    • Activities: What an individual chooses to do.
    • Culture: The culture an individual is raised in profoundly shapes their sense of self, sometimes leading to a desire to align with or diverge from that culture.
    • Personal Experiences: Life experiences, including trauma or the family environment, significantly impact identity formation.
    • Beliefs: Personal beliefs about characteristics such as race, ethnicity, gender, and sexual orientation are integral to self-identity.

Erik Erikson's Theory of Psychosocial Development: Identity vs. Role Confusion

  • Fifth Stage: According to Erik Erikson, adolescents are in the fifth stage of psychosocial development: Identity vs. Role Confusion. He considered this a fundamental stage.
  • Psychosocial Crisis: This stage challenges adolescents to actively develop an identity by exploring various options and roles (racial, ethnic, gender, sexual, vocational, etc.). This quest for "who am I?" is particularly crucial during adolescence and emerging adulthood (ages 18 to 24).
  • Resolution: Erikson believed that each developmental stage presents a psychosocial crisis requiring resolution, ideally leading to a more positive outcome. In this stage, adolescents should resolve the conflict by moving towards a clear sense of identity rather than role confusion.
  • Real-world Examples: This stage manifests as confusion about career paths (e.g., choosing a major) or relationship choices (e.g., dating to understand what one desires in a lifelong partner), where individuals explore diverse options before settling on a defined identity.

Culture and Ethnicity in Identity

  • Identity Shaping: Culture significantly shapes identity during adolescence. The culture of upbringing can influence personal values and aspirations, sometimes leading individuals to either embrace or challenge their cultural heritage.
  • Acceptance or Rejection: Culture also dictates whether an individual's emerging identity will be accepted or rejected. For example, a person's sexual orientation might be met with severe rejection and consequences in certain cultural contexts (e.g., being gay in strictly conservative societies), potentially forcing them to suppress parts of their identity or seek out new cultural subgroups that are more accepting.

Relationship Between Parents and Adolescents

  • Increased Conflict: As adolescents develop their own identities and begin to think more independently, conflict with parents often increases. Adolescents may perceive parents as intrusive or controlling, while parents may struggle to understand their child's burgeoning autonomy.
  • Peer Influence: Peers play a more crucial role in identity development during adolescence than parents. Peer groups offer a space for self-exploration and validation outside of the family unit.
  • Transactional Analysis: This concept suggests that individuals play roles of adult, parent, and child. In adolescence, parents often remain in the 'parent' role while the adolescent transitions from the 'child' role towards the 'adult' role. To reduce conflict, ideally, parents should also shift towards an 'adult' role to meet the adolescent midway, fostering a more balanced dynamic.
